While the majority of this road ride will likely not be in English, this looks more like a typical US informal group ride: Every Saturday at 14:00 (2PM) from Tempo-Sport in Thalwil. They indicate the ride will be between 2 and 3 hours. I know the shop owners and they do speak english. See the PDF through the attached link (sorry for the German): http://www.tempo-sport.ch/infos/even...nvelotref.html

Given the difficulty this website has had in setting up regular road rides, this is likely a good alternative.
